STOVE-EDUCT.

SPECIFICATION. forming part of Letters Patent No. 247,371, dated September 20, 1881.

Application filed August 8, 1881. (No model.)

To all whom it may concern.-

Be it known that I, JOHN T. LLOYD, of Boston, of the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Stove-Educts; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which Figure l is a side elevation, Fig. 2 a front view, Fig. 3 a vertical section, and Fig. 4 a horizontal section, of an educt of my improved kind. Fig. 5 is hereinafter explained.

- The said educt is for so adapting a stove to an opening or thimble of a fire-place or chimney-flue that the smoke and volatile products of combustion escaping from the stove may pass into such fire-place or flue and be carried off into the atmosphere.

It not infrequently happens that the educt of a cooking-stove is either higher or lower than the thimble or opening of a flue of a chimney, in which case a pipe with one or more elbows becomes essential to the proper connection of the educt with the flue.

\Vith my invention, the nature of which is defined by the claims hereinafter set forth, the adaptation of a stove to a chimney can easily be efiected.

In the drawings, A denotes a smoke-receiver consisting of a pipe, a, open at its opposite ends, and elliptical, or thereabout, inits transverse section. To each of the ends there is a removable cover, 1), adapted to fit into the pipe. In front of the pipe is a rectangular or elongated opening, 0, extending nearly throughout the length of the pipe, there being to such opening a sliding thimble, B, and a series of plates, 0, they being adapted to slide lengthwise of the pipe in parallel guides D D arranged on opposite sides of the opening.

Fig. 5 is a front view of the receiver A as it appears without its' adjustable slides and thimble.

At its rear the receiver A is provided with another but circular opening, P, which is circumscribed by a short cylindrical pipe or flange, R, extending from it, as shown, an elbow or induction-pipe, S, being fitted on the said flange It, and extended therefrom in manner as represented. Atits lower end the pipe S is to be adapted to the eduction-passage at the upper part of a stove.

When the educt of the stove is at the lower part of such stove the receiver A may have one of its covers removed, and be at such end fitted directly upon the educt. In either case the movable thimble is to be adapted to the proper height or distance to fit to and lead into the opening of the flue or fire-place, or a pipe or conduit extending therefrom.

When the elbow-pipe is not required to be used the opening at the rear of the receiver may be closed by a suitable cap or cover.

From the above it will be seen that the receiver may be used either end upward, in which case the lower end cover may be removed and the receiver be fitted to an educt at the lower part of a stove, or when the educt is at the top of the stove the elbow-pipe may be employed to make the connection between the stove and the receiver. The thimble having been adapted to its proper altitude, the part of the opening 0 that may be above and be low the thimble may be closed by the slides. The smoke, after passing from the stove into the receiver,will escape therefrom through the thimble.

I am aware that to adapt the eduction of a stove to a fire-place a plate covering the front of such fire-place and provided with an opening and an adjustable thimble and plates, as hereinbefore described, have been used, and therefore I make no claim thereto, my invention resting on the smokc-receiver and its adjuncts, as explained.

what therefore I claim as of my invention is as follows, viz:

1. The smoke-receiver A, open at its opposite ends and in its front and rear, as described, and provided with the end covers, I), and the adjustable thimble B and slides all arranged, adapted, and to operate substantially as and for the purpose set forth.

2. The combination of the elbow-pipe S with the smoke-receiver A, open at its opposite ends and its front and rear, and provided with the end covers, I), and the adjustable thimble B and slides 0, all being arranged and adapted and to operate substantially as and for the purpose or purposes set forth.
